Changes in left ventricular mass and cardiovascular risk factors after kidney transplantation

الملخص EN

Left ventricular hypertrophy (LVH), the most common structural cardiac complication, is the single most important cause for sudden cardiac death.

There are no published data from India looking at the changes in left ventricular mass and cardiac dysfunction after kidney transplantation.

We aimed to determine the changes in the left ventricular mass and other cardiovascular risk factors in kidney transplant recipients.

This was a prospective observational study.

All patients who underwent kidney transplantation at Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, during the study period were included in the study.

Measurement of clinical and biochemical parameters and echocardiography were done before, six months, and one year after transplantation.

There was significant reduction in LV mass index (124.8 ± 39 vs.

102.2 ± 24.4 g/m2, P <0.001) and improvement in ejection fraction (57.8 ± 7 vs.

60.1 ± 1.9, P = 0.015) at the end of six months.

There were significant differences in the mean hemoglobin, systolic, and diastolic blood pressures (P <0.001) during the study.

There was also a significant reduction in the number of antihypertensive drugs required for blood pressure control.

There was a significant reduction in LVH in the study group.

There was also improvement in systolic and diastolic functions of the heart.

There was also a significant improvement in blood pressure control both in terms of mean blood pressure levels as well as in terms of the number of anti-hypertensive drugs needed for blood pressure control.

Renal transplantation ameliorates cardiovascular risk in renal transplant recipients.
